- Dictaphone Shaving Machine, Type S, Model 10, circa 1929 - Dictaphones and Ediphones were sound recording devices largely used for oral dictation in business settings. In this scenario, wax cylinder recordings were passed to a secretary, who listened to the recording with a playback-only transcriber and then typed up notes. A shaving machine, such as this one, scraped the previously inscribed layer away allowing a wax cylinder to be reused over 100 times.

- Patent Model of Lamp Extinguisher, 1878 - From 1790 to 1880, the U.S. Patent Office required applicants to submit a miniature model along with diagrams and written descriptions detailing the operation of their invention. Patent models could be no larger than 12" by 12" by 12". Though they were usually not operational, these models helped explain an inventor's idea and protect it from competitors.

- Faradon Variable Mica Condenser, Model UC-1819, 1920-1925 - Early radios containing vacuum tubes needed both AC (alternating current) and DC (direct current) electrical power to operate. Condensers (also known as capacitors) allow alternating electrical currents to pass while blocking direct currents. Condensers can block, pass, filter and tune the various currents of the radio.
